SPECIFICATION forming part'of Letters Patent No. 508,974, dated November 21, 1893 Application filed October 5, 1892. Serial Nb. 447,953. (No model.)

To all rv/wntit may concern."

Be it known that I, ALBERT DE M. RAMAO- OIOTTI, a citizen of the United States, residing at New York city, in the county and State of New York, executor of the estate of FRAN- CIS RAMACOIOTTI, deceased, late a resident of the city, county, and State of New York, do hereby declare that the said FRANCIS RAMAo- OIOTTI in his life-time invented a new and useful Improvement in Machines for Swaging Wire for Musical lnstruments, of which the following is a full, clear, and exact description.

The invention relates to an improvement I 5 in swaging machines, and especially to an improvement in machines for swaging wire strings for musical instruments.

The object of the invention is to provide a machine, simple, durable and economic in 20, construction, and capable of being conveniently manipulated. A further object of the invention is to provide a machine capable of being adjusted to successfully operate upon strings of varione lengths and of high temper, leaving the strings at theirfiattened surfaces smooth and flawless.

The invention consists in the novel construction and combination of the several 0. parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures andletters of referonce indicate corresponding parts in all the views.

Figure l is a partial side elevation of the machine, and a partial longitudinal portion through one of its sections. view of the machine. section taken practically on the line 33 of Fig. 2. Fig. t is a vertical longitudical section taken practically on the line 4L4 of Fig. 2. Fig. 5 is a horizontal section taken essen- 5 tially on the line 5-5 of Fig. 4:. Fig. 6 is a vertical transverse section on the line 6-'-6 of Fig. 5. Figs. 7 and 8- are perspective views of the swaging blocks and their carriers; and Fig. 9 is a perspective view of a section of wire, illustrating the surfaces flattened thereon by the machine.

d Fig. 2 is a plan 40 Fig. 3 is a transverse Heretofore steel wire strings for musical instruments have been flattened by a hand hammer. When strings of high temper, and the majorit'y are such, are treated in this manner,-the"flattened surfaces are full-of flaws, and the string is thereby rendered unreliable, that is, in many instances the wire breaks at the flattened surfaces either under the hammer or the moment the wire is vi- 6o brated or bent even to a slight degree.

The prime object of this invention is to provide a machine which will quickly flatten steel music wire of the highest temper without in the slightest degree injuring the fiber of the wire, and whereby the flattened surfaces will be particularly evenly made, renderingit not only possible to cover the string at its pressed or flattened points but also to enhance thebeauty of the string by reason of the evenness of the covering.

The frame of the machine consists of a se-. ries of uprights 10, the end uprights being connected at the top by cross bars 11; and the uprights at each side,'as.the said uprights are arranged in rows, are'adapted to support bed plates 12 and 13, these bedplatesanduprights constituting practically the base frame of the machine. The bed plates are parallel,

and each of them is provided with a groove 14, extending through from end to end. This groove is practically inverted T-shape in cross section, as shown in Fig. 3, whereby the lower portion of the groove is its wider portion. At one end of. the machine an exten- 85, sion 15, is made, the said extension consisting preferably of two uprights ld connected .at the top by a cross bar. 17. t

Between the center of the machine and the forward bed plate 1.3 a rack 18, is horizon- 9o tally supported, the rack extending longitudinally of the machine frame, practically from end to end. This rack may be sustained in its horizontal position in any suitable or approved manner, but usuallythis is .95

effected through the medium of horizontal brackets 19, these brackets being secured to the rack and to the forward bed plate, as shown in Figs. 2 and 3.

The swaging device A, adapted to be sup- I00 ported by and slid upon the base frame may be described as follows: A body plate B, is

formed, as shown best in Figs. 4, 5 and 6, which body plateis practically rectangular in general contour and of a length sufficient to enable it to extend transversely across the base frame over each of the bed plates 12 and 13. The rear portion 20 of the'body plate is flat and somewhat thin, and this portion, is provided with longitudinal flanges 21 at the sides, while the forward portion of the body plate of the swaging machine is of peculiar shape. This portion is much thicker than the rear portion, and is shaped somewhat rectangularly; and this enlarged portion 22 of the base, at its. inner face, is providedwith two recesses, the inner recess beingdesignated as 23, and its contour is best shown in Fig. 6, in'which the recess will be observed to be somewhat rectangular, but

the base wall, at its side is beveled down-.

ward, as indicated at 24, forming thereby what may be termeda center block 25.

The .other recess is'forw-ard of the recess 23,

as shown in Figs. 2 and 3, and'is designated ward or outer wall thereof is inclined. recess 23, is adapted to receive a carrier D,

The inner portion of this recess is; rectangular in general contour, but the ford The in which one of the swaging jaws or blocks 27, is located; and the other recess is adapted to carry an opposing carrier D, which sup-. ports a second swaging block or jaw 28,; adapted to act in conjunction with the block or jaw 27.

These carriers and-their jaws or:

blocks are shown in detail in Figs. 7 and.

8, and-will be hereinafter more minutely described.

frame of. the machine; and to that end bolts 29, ordinarily three in number, are passed through the base plateB at its ends, one bolt being located=at the central portion of'the, rear end, and two bolts at the forward end; The forward bolts pass downward into the slot or groove 14 in the forward bed plate 13 f of the, frame, while the rear bolt is similarly% located in the groove of the rear bed plate of} the machine. By loosening the-nuts which are placed upon the upper ends of these bolts, the swaging device or machine may beslid toward the center of the base frame, or in di-. rection of its upper end, and when properly:

located it may be effectually held in the posif j tion in whichit is placedby screwing up the nuts upon. the bolts.

been loosened, the lateral adjustment offthe .1

swagingdevice or machine is accomplished After the nuts have through the medium ofa hand-wheel30, which handwheel islocated at the front=ofithe ma.-

chine, and is fastupon a shaft 31, which ex-. tends rearward through the bottom part of T the thicker portion ofthe bedplate B;as

shown in Fig.4; and this shaftat its inner end is provided with an attached pinion 32,

1L said pinion engagingwith-theteeth of 3 th e. rack 18.

' thereof;

A drive shaft 33, is journaled in suitable bearings at'the ends. of the main frame and at the ends of the extension 15 of said frame. This shaft is preferably located back of the rack and beneath the base B of the device or machine.

A sleeve 34, isheldtoslide upon the shaft 33, and this sleeve carries at or near one end a pinion '35, which may either be attached to the sleeve or constitute an integral portion The sleeve is connected with the under portion of the base B of the machine or device by means of a strap 36, as shown in- Fig. 1, which connection enables the sleeve torevoive freely upon the shaft 33, yet when the base is slid laterally'in direction of either end of the base frame the sleeve is carried with it. The pinion '35 of the sleeve meshes with a large gear wheel 37, fast upon the outer end of a short shaft 38, which shaft is journaled in suitable boxes 39, formed in or uponthe flanges 21 of thebase A,'as is likewise best shown in Fig. 1.

Between the flanges andupon the-shaft 38, a pitman 40, is eceentrically attached, the pitman where it receives the shaft being provided' with a recess, as shown in Fig. 4, which receives the forward face of the shaft, while a strap 41, is made to embrace the rear face of the shaft, the said strap being screwed or otherwiser'emovably attached to the eccentric crank. The pitman is adapted for direct attachment to the carrier D, supporting the jaw or block 27. This carrier isshown in detail in Fig. 7, and consists of a body portion 43 and arms 44, projecting from therearward or inner end of the body portion, one at each side, and these arms are-each provided preferably with an elongated opening 45,'the openings being in alignment; and through the larger or circular portions of these openings, and through a suitable opening in the forward end of the pitman 40, a pin 46,' is passed, the pin being the connecting'medium between the jaw carrier D and the pitman, as shown in Figs. 4 and 5. The elongations of the openings 45 are made to receive wear plates 47, shown in position in- Fig.5; and

these wear plate s are adjusted toward the pin '46, to compensate for wearupon the latter, by means of screws 48," said screws being passed through the extremitiesof the arms 44 of the carrierD. I I

The carrier is adapted, as has heretofore been stated, to slide in the recess 23 ,located in the forward orthicker portion of the base B; therefore, the under face of the carrier D,

'is provided with iunerbeveled side faces, as

the carrier in-cross section must correspond 1' to the cross'sectiona'lshape of the recess 23, the carrier resting upon the center block. 25, as show-n-in -Fig. 6.

In order'that" the carrier block m'ay, not leave-its recess, bindingplates 49,are attachedto the upper side faces of'the bed sec.-

'tion 22, the plates extending therefrom over the carrier, as shown in'Figs. 2 and 6. The

section, and is fitted in a correspondingly shaped recess 50, formed in jaw or block 27, adapted to engage with the wire is somewhat of dove-tail shape incross the carrier.

The carrier D, illustrated in detail in Fig.

8, com prises two sections d and d, the section thatis, to or from the inner jaw. It may be here stated that the base wall of the Outer recess 26 is on a level with the base wall of the inner recess 23; in fact, the base walls of .the two recesses are continuous, and there-' fore the recesses heretofore described as 23 and26, constitute practically a single recess,

but is divided for convenience in description into two sections 23 and 26, the inner section ;23, receiving the carrier D, and the outer or forward section 26 the carrier D.

. The rear section d of the carrier D, comprises a plate 51, having-an inner wedge face 52, the wedge face being provided with a longitudinal rib 53; preferably dove-tail shape The section d of the car-' in cross section. rier consists of a block essentially rectangular in shape, of less length than the wedge face of the section 61; and this block in one face is provided with a groove or channel 54,

receivingthe rib 53, thechanneled face of wedge; and the extended end is provided with an attached or integral bolt 55, carrying a thumb nut 56. The jaw or block 28, adapted toe'ngage with the wire to be swaged ispref erably dove-tail shaped in cross section, and

fitted in a correspondingly shaped groove 57, formed in the inner face of the block section d. Both of the blocks or jaws 27 and 28, are

held in position in their carriers by screws 58, or likedevices, passed through one surface of the carriers and into the blocks, as is likewise shown in Figs. 5 and 8.

The recessed section 26 in which the carrier D, is placed is so shaped that the-block section d may have movement to and from the carrier D; but the section d of the can rier D, has movement transversely of the base, that is, in a direction at rightangles to the movement of the block section 01'; and this movement of the wedge section (1, is accomplished by passing the bolt 55, through a recess 58 in the top of the base B, as shown in Fig. 5, and between lugs 59, adjacent to the recess, the thumb nut 56 being located between the lugs 59 and the outer face of that portion of the base in which the recess 58, is located, as islikewise best shown in Fig. 5. Thus by turning the thumb nut 56, the wedge section may bemade to slide in direction of either side of the base, and the block section d, connected with the wedge will be carried in direction of either the front or the rear of the base. When the carriers D and D, are

the inner face of In the process of swaging the wire two such machines or devices A, as have been heretofore described, are located upon the base frame, one at each side of the center of the frame; and the wire string E to be operated upon is passed between the opposing jaws or blocks of each machine; butit will be understood that each machineis complete inwitself, and if but one surface ofthe wire is to be swaged a single machine only need be employed; but usually wire strings are flattened at several points in their length, more particularly at two points, and therefore two machines are shown in the drawings as mounted upon the base.

In order that a wire string may be expeditiously manipulated in a manner to present it properly to the swaging jaws or blocks, one end of the wire string is twisted to form an eye 61, as shown in Fig. 2; and this eye is made to engage with 'a-hook 62, formed upon a standard 63, the standard being adjustable upon the forward bed plate 13; and the location of the hook 62 is such that'it is in alignment with the space between theswaging blocks or jaws of the machine nearest to the standard. The wire after-having been passed between the swaging jaws or blocks of one machine, is carried between the jaws or ICC blocksfof the next machine. Theadjustrnent v of the machines laterally upon the base frame is made either before or after the wire is placed in the proper position. When the wires are placed in position, the swaging blocks or jaws are spaced some distance apart; and one revolution of the shaft 33is sufficient to carry the jaws or'blocks together, that is, the sliding block 27, in practical engagement with the fixedblock 28; and this movement will'produce a flattened surface upon opposite sides of the wire string, the said surfaces being'shown at ein Fig. 9. Ordinarily the wires are pressed but once between the jaws, but the swaging may be repeated if exceedingly thick wire is used until the proper reduction has been obtained. When more than one swaging machine or device is employed, they all operate alternately'or simultaneously as may be desired.

The'fibers of the wire are not injured when a machine is used constructed as above described, as equal pressure is brought to bear at both sides of the surface operated upon, and the blocks or jaws are smooth; therefore the surface is not only pressed but it may be said to be ironed out. The adjustment to accomplish the pressing or flattening of wire of difierent thickness, or to cause amore or less reduced-surface in the wire, is made by carrying the wedge section (1 of the essentially fixed carrier D inward or outward;

Ashasheretofore been stated, this machine is not only simple, durable-an'd 'economic, but it is capable of being manipulated inanexpeditiousand convenient manner, and" thestrings" flattened thereon are'not in t'h'o'least' injured, but the flattened surfaces are so smoothed that they maybe covered and presentla most sightly appearance.

Having thus described the invention, what is claimed as new, and desired tobesec'ured by Letters Patent, is-
